Hi Lads. Have enjoyed this forum which has helped me rebuild old mowers etc which I bought and sold as a hobby. I have bought a BSA 650 cc Thunderbolt which was in boxes, totally in bits. It belonged to a guy who died in 2012 in Southend. I am going totally restore it and ignore mowers for a while. It might not be pedestrian machine but it will plough a field one day, I hope. Regards to everyone that has helped me. Colin.

I recent visited the ALDI supermarket to buy some bits. I noticed that they were selling aerosols 400 ml in various colours at about £2.50 each. I bought a couple and left them in the garage for a rainy day. This week I used it for a project, it is extremely similar to dark green Hayter and much cheaper. Called Deco Style Metal Spray Paint made in Germany ( High Gloss ), made for ALDI. As the Forum is so quiet I thought I would share this.

Think I have solved it. Took two wheels off an old Hayterette. The are slightly bigger diameter but the bearing shaft is the same size. They have caged roller bearings with cones and fit well. I don't suppose these new plastic wheels are as strong as the old steel ones, will have to see.

Plodding on with the restoration. front wheel bearings have disintegrated and the wheels are not much better. Do any more modern wheels fit, I am aware this is a heavy machine, however about 80% of the weight sits on the back wheels ( They are in good condition ). I was wondering if the Hayterette wheels may do the job. Thanks lads

Yep a Sterkins, Looks like a Mountfield, expensive controls and a B & S Quattro. I thought the same as you, got it for £10, body rotten, good engine ready to go on one of my Hayterettes. I can't even find Sterkins on Google. We learn every day.

Only left the cleaner in the tank for short while, then thoroughly rinsed it. Stormin, My filter is not like the one in your thread. Mine is 5HP and more like a larger version of the Sprint filter, similar shape. Unfortunately I cannot upload photos.Regards ..

Cleaned the tank with brick cleaner, then paraffin. Filled the tank, put a drop of fuel in the carb and it actually started first time. It then ran off along my drive and hit my car before it stopped. These old beasts have some power. Has anyone got the B & S part number for the air filter please. Regards.
